The present invention relates to a composition in which an oxide or hydroxide of a specific metal is arranged around flame-resistant fibers derived from acrylic fibers. More specifically, the present invention relates to a composition in which hydrogen cyanide is not substantially generated when flame-resistant fibers are heated. Flame-resistant fibers made from polyacrylonitrile fibers are produced by heating fibers obtained from polymers containing 85 mol% or more of acrylonitrile at 200 to 300°C for several tens of minutes to several hundred minutes in an oxidizing atmosphere such as air.
Manufactured by known methods, density 1.35-1.6
g/cc and is a fiber with excellent flame resistance. This material has the excellent property of not melting and retaining its shape even when heated in air in a temperature range of 400°C or higher and below the sublimation temperature of carbon. There is. For this reason, it has begun to be used to prevent fires caused by welding sparks, as well as in fire-retardant clothing, fire-retardant curtains, kitchen clothing, gloves, and wall materials. However, when flame-resistant fibers are heated to 300° C. or higher, hydrogen cyanide is generated as one of the decomposed gases, and their use is sometimes limited from the standpoint of safety and health. As a result of intensive study on the problem of pyrolysis gas generation from flame-resistant fibers, the inventors of the present invention have found that by arranging a specific substance around flame-resistant fibers, hydrogen cyanide generated during heating can be decomposed. It has been found that the cracked gas can contain no or almost no hydrogen cyanide gas. The present invention is as follows. At least 5% (by weight) of Al, Mg, Ca,
A composition in which a single compound of Zn, Fe oxide or hydroxide, or a mixture of these compounds is arranged around flame-resistant fibers derived from acrylic fibers. The flame-resistant fiber used in the present invention is produced by polymerizing and spinning 85 mol% or more of acrylonitrile and known vinyl monomers such as methyl acrylate, acrylamide, vinyl acetate, sodium methallylsulfonate, itaconic acid, and acrylic acid. The obtained known acrylic fibers are heated in air or an oxidizing atmosphere to
A fiber obtained by heat treatment at 300°C under a tension of 1 to 200 mg/d for 10 to 20 minutes, with a tensile strength (dry) of 0.5 to
3g/d, tensile elongation 5-40%, density 1.35-1.6
g/cc. The flame-resistant fiber has a single fiber thickness.
Small tow consisting of 0.5 to 3.0 denier and 1000 to 20,000 fibers, and 20,000 to 20,000 fibers with the same fiber thickness.
There is a large tow consisting of 500,000 pieces. The flame-resistant fiber is used as a strand, or processed into the form of spun yarn, knitted fabric, felt, non-woven fabric, paper, etc., or used as a chopped fiber with a length of 0.1 to 10 mm. In the present invention, the oxides or hydroxides of Al, Mg, Ca, Zn, and Fe include, for example, aluminum oxide, magnesium oxide, calcium oxide, zinc oxide, ferric oxide, aluminum hydroxide, magnesium hydroxide, water Calcium oxide and hydrated compounds thereof. In the present invention, single or mixtures of these compounds are placed around the flame resistant fibers. These single substances or mixtures usually range from 0.01 to
100μm granular material or liquid material, etc.
It may be alumina fiber, glass fiber, or asbestos containing 70% or more (by weight) of aluminum oxide. The composition in the present invention is 0.1 to 10 mm of metal oxide or hydroxide particles or alumina fibers.
strands of flame-resistant fibers, woven fabrics, knitted fabrics, felts, non-woven fabrics,
It is placed around flame-resistant fibers by attaching or attaching them to paper, or by mixing chopped pieces of flame-resistant fibers. Here, arranging a metal oxide or hydroxide around a flame-resistant fiber by adhering, impregnating, or mixing does not necessarily mean adhering or impregnating it so as to completely cover a single fiber of the flame-resistant fiber; Adhering to, adhering to, or coating the outer periphery of a strand of single fibers, spun yarn, etc., or the surface of a processed product such as woven fabric, knitted fabric, felt, nonwoven fabric, paper, or glass fiber, asbestos, alumina fiber, etc. This means that cloth, felt, or mat is placed on the upper or lower surface of flame-resistant fibers and integrated. In the present invention, it is necessary to use the metal oxide or hydroxide alone or in combination of two or more, or to use the metal oxide and hydroxide in combination to make it 5% (by weight) or more. If it is less than % (by weight), hydrogen cyanide will be generated in large quantities, which poses safety and health problems. In addition, as a method for adhering, impregnating, and mixing, in addition to the usual dipping method, showering method, and coating method, a kneading method and the like can be used. For example, a metal oxide or hydroxide is dispersed in water, or a dispersion prepared by dispersing it in water, acetone, ethanol, dichloroethane, etc. together with a binder as described above is attached or impregnated, and then dried. , a method of desolvation, or a method in which metal oxides or hydroxides are mixed with flame-resistant chop fibers and, if necessary, powders such as calcium sulfate, calcium silicate, calcium carbonate, etc. are added to water as fillers. A method of kneading in the presence of the compound and then forming a solidified molded product can be adopted. In the present invention, a particularly preferred composition is aluminum hydroxide or aluminum oxide.
(by weight) and 5-20% (by weight) of silicone resin are impregnated or coated with flame-resistant fiber fabrics, felts, and non-woven fabrics. Examples will be described in more detail below along with comparative examples. "Part" and "%" in the examples indicate weight unless otherwise specified. Example 1 Acrylic fiber (1.5 denier, 500,000 filament tow, consisting of 95 mol% acrylonitrile and 5 mol% methyl acrylate, strength 3.5 g/d,
(elongation 15%) was heat-treated in air at 245℃ and tension 70m g/d for 3 hours to obtain 1.9 denier and strength 3g/d.
d. A flame-resistant fiber with an elongation of 20% and a density of 1.39 g/cc was obtained. From this fiber, a twin yarn of 11.3 count (cotton count) was created by tow spinning, and further 8 pieces of satin yarn,
The fabric was 300 g/m 2 . On the other hand, 20 parts of aluminum hydroxide (average particle size 50 μm) and silicone resin (manufactured by Toshiba Silicon Co., Ltd., binder) emulsion
100 parts (purity: 30%) and stirred with a high-speed homomixer to uniformly disperse the liquid, which was then applied to the flame-resistant fibers, dried at 120°C, and then heated to 200°C.
Heat treated for 30 minutes at ℃ and aluminum hydroxide 1%, 7
Fabric processed products were made with four types of impregnation amounts: %, 15%, and 30%. Each strength is 15, 18, 20, 24Kg/
cm (measurement method according to JIS-1096). 1g of the above processed product is heated in air using a Bunsen burner (propane gas) flame at 840℃.
After heating for 10 minutes, the amount of hydrogen cyanide in the generated cracked gas was measured, and the results shown in Table 1 were obtained. According to this, except for 1% impregnated products (comparative example),
It can be seen that almost no hydrogen cyanide was generated.

After kneading 800 parts of this chip product with 200 parts of alumina fiber (containing 85% aluminum oxide), 3000 parts of calcium sulfate, and 100 parts of water,
It was pressed into a plate shape with a thickness of 5 mm, width of 50 mm, and length of 200 mm, and then dried at 200°C to form a flat plate. When this flat plate was heated to 400°C, cracked gas was generated and the weight decreased by 20%, but no hydrogen cyanide was detected as the cracked gas. In contrast, a flat plate that does not contain alumina fibers is 5mg/g.
(flat plate) hydrogen cyanide was detected. Example 3 Acrylic fiber (acrylonitrile 97 mol%,
